can -oiiinnitk Applicationfled November 22, 1,926; Sera1-\No. 149,939.

This invention 'relates to a certain new and usefulimprovement in eainopeners and has for its object the provision of `a device oi' tool of the type stated that is simple, inexpensive, and compact inform and constructioinavhich is conveniently manually operable, and which is eitlicientin the per- Y forinance of its intended functions.

Y continuously And iviththe above and other objects in view, iny invention resides in the novel features of form, construct-ion, arrangement, and combination of parts hereinafter de? scribed and pointed out in the claims.

In the accompanying'draiviiig,

Figure' l is a transversesectional View, in cutting position upon a can, frag-mentally shown, of a can-opener embodying my invention 5 Figure 2 and p Figure 3 is a fragmental plan view of a slightly modified form of can-opener einbodying my invention.

Referring now more in detail and by ref-v erence characters to the drawing, my new is a plan View of the can-opener;

can-opener includes a body-member con- V structed of suitable metallic material and in the form of a plate l preferably, of generally or approximately circular contour, as

best seen in Figure 2. Preferably, further,v

as shown, the plate l is formed or provided throughout its margin With a lateral flange 2.

Formed or provided radially in plate l, is a closed-end slot 3, and adapted for ad-k justable movement in slot 3, in a preferably threaded pin or stein 4f of a depending member or enlargement 5 arouated transversely relatively to slot 3 for ean-gripping or engagement in co-operation with the opposed portion of flange 2, and having threaded engagement With stem 4 for impingingly engaging the plate l for releasably` retaining the stem l and its Vdepending can-gripping member 5 in relatively adjusted position,

is a. knob 6, which is adapted to also func-V tion as a manual gripping-member for, the can-opener in facilitating can opening or cutting operations.

Adapted for co-operation with the plate l in can-cutting operations, is a suitable preferably renewable blade which may, as shown in Figures'l and 2, be of angular formation in side elevation, integrally including a flat shank `7 land a down-turned flat end ork cutting-portion 8or, as shown lthe margin of the can;

in Figure 3, be in the form. of a disk 9` hav ing a hub-portion l0. In one instance, the plate l, preferably in radial alignment with, and opposite theinner end of, the -slot 3,

is formed or provided with a blade-seat .in

the form of a pair of spaced relatively flat transversely disposed rigid straps ll for slidably acconnnodating'and engaging With the flat `shank 7 of the blade,the plate l With its flange 2 being rout Iaivay or recessed upon its margin, as at 12,'for accommodating the depending end-portion 8 of the blade. In the other instance, the plate l with its flange 2 is cut-away or recessedA upon its margin, as at 13, for accommodating the dislnblade 9 and its hub 410, andy formed or provided with a blade-,seat preferably in the form of a suitably elongated semi-cylindrical strap ll for slidably raccominodating the shank of the blade which is in the forni of a rstub shaft l5, which latter is projected through the flisk 9 and its hub l0 and into the sea le. and Which provides a supporting shaft for the blade. In both instances, Will be noted, Lwhile the respective blades are yfirmly supported and carried by the plate l for can-cuttingoperations, Without the necessity ofthe employment of `any additional meirbers or means, both types of blades are readily removable or-detachable fromthe plate for, suoli` repair or replacement as may become necessary. Y In use or operation, the plate 1 is disposed .the lingers, the blade is manually rotatorily moved bodily upon and relatively to the can and the blade consequently shiftediaround fects a clean cut of the can-Wall 16, without any remaining ragged edges in the cutvcan.

In such operations, the flange 2 of the'` plate l facilitates gripping engagementby Such operation ef-V the hand with the plate, and both the plate l and its flange 2 prevent the splashing or spurtingfrom thercan of any contained liquid or other contents. Preferably the vali-gripping;` member iis Yformed with aK .inwardly presented projection 5 for 'lieilig tating;- tirm engagement between the member 5 and the bead of the can;

My new eainopener may be need with satetyk and convenience in the Cutting ot lid` from either hot or cold cane, is readily land easily manipulated in Cut-ting oirieratione,

'and has been found exceedingly. ell'ieient in the performance ot its int-endedl functions.

l am aware that changes in the forni, Construction, arrangement, and combination of the. several parte of my new Can-Opener may be made and substituted l'or tho-se herein shown and described without. departing; from the nature and principle oit my inrention.

Having' time deeeribed my new invention` what l claim and desire to secure by Letters Patent is:

l. A eaneopener including` a plate having a laterally iianged portion. a cnttinfgblade Carried by the plate and located adjacent adapted 'for bodily the margin of the plate, 'the plate being disposition and move ment tlatwiee upon a lan for shitting the blade in can-Cutting operations, and means carried by the plate ttor (3o-operation with eaid iianged portion in adjuetably adapting the can-opener for engagement. with Cans of dilierentdiameters.

2. A eainopener including a. plate having,` a radial -slot and a. laterally flanged portion, a cutting-blade carried by the plate and located adjacent the margin of the plate, the plate beingI adapted for bodily disposition and movement fiatwiee upon a can for shiftingthe blade in can-enttinpj ope 1atione, and means including` an arcuate member having a Stem Working in Said .alot for eo-operation with Said flanged portion in adjust-ably adapting the can-opener l'or engagement with Cans of different diameters.

In testimony whereof, I have hereunto signed my name to this` specification.

PAUL `WERNER.
